PERMANENT-MAGNET ROTOR AND ROTATING MACHINE COMPRISING SUCH A ROTOR

摘要

The invention relates to a rotor (1) of a rotating electric machine, having permanent magnets (7) and flux concentration. The rotor comprises a rotor casing (3) having radially oriented housings (5) in which the permanent magnets (7) are disposed. The width of each housing (5) over at least one portion that is in contact with the magnet (7) decreases extending away from the axis of the rotor (1). Moreover, each housing (5) opens at its radially inner end into a hole (6) extending from both sides of a midplane (M) of the housing (5).
